Frequency |
Axes |
Every far field requires a valid frequency axis. (Hz) |
Spatial Axis 1 |
Axes |
The first spatial axis, depending on the coordinate system.
- Theta (when using spherical coordinates) is the elevation angle component relative to the local workplane. The vertical position is located at
θ=0∘
. (deg)
- X (when using Cartesian coordinates) is the
u
component of the unit vector relative to the local workplane.
|
Spatial Axis 2 |
Axes |
The second spatial axis, depending on the coordinate system.
- Phi (when using spherical coordinates) is the azimuthal angle component relative to the local workplane. (deg)
- Y (when using Cartesian coordinates) is the
v
component of the unit vector relative to the local workplane.
